Answer 1

for adding NSString in NSMutableArray is like this
NSString *str = #"object";
NSMutableArray *loArr = [[NSMutableArray alloc] init];
[loArr addObject:str];
In your code Why are you using self.array ? just write like this. [array addObject:photoID];

Answer 2

self keyword is used for global variables but here in your code
"array" is a local variable .So need of self.array
[array addObject:photoID];
Before adding check that photoID is nil or not
if (photoID.length > 0) {
[array addObject:photoID];
}

I observe that in your code. you declare mutable array in local scope.
So just use
[array addObject:photoID];
Instead of
[self.array addObject:photoID];
May be you are create property for this array with same name, then you need to alloc it.
If you create a property for this then remove local declaration and alloc array like this.
self.array=[[NSMutableArray alloc]init];
and then use
[self.array addObject:photoID];
